74347-26-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74347-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,4 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74347-26:
(7*7)+(6*4)+(5*3)+(4*4)+(3*7)+(2*2)+(1*6)=135
135 % 10 = 5
So 74347-26-5 is a valid CAS Registry Number.

3-chloropropyl and 4-chlorobutyl phenyl ethers as sources of 1,3-dilithiopropane and 1,4-dilithiobutane: Sequential reaction with carbonyl compounds

Foubelo, Francisco,Saleh, Sadiq A.,Yus, Miguel

, p. 3478 - 3483 (2007/10/03)

The reaction of 3-chloropropyl and 4-chlorobutyl phenyl ethers (1) with lithium powder and a catalytic amount of DTBB (5% molar) in THF at - 78 °C followed by successive treatment with a carbonyl compound [R1R2CO = ButCHO, Me2CO, (CH2)5CO, (-)-menthone] at -78 to 20 °C and, after 1.5 h at this temperature, with a second one [R3R4CO = Bu1CHO, PhCHO, Me2CO, MeCOPrn, (CH2)5CO, (-)-menthone] at -78 °C leads, after hydrolysis with water, to the corresponding 1,5-and 1,6-diols (2). Because of the competition of two different reductive cleavages, 1,4- and 1,5-diols 3 were also obtained as side-reaction products.
